@mfalkvidd Getting it to run on the ATmega328PB seems like it might be worthwhile upgrade. Actually, it's so similar maybe it already does. The atmega328pb is a slightly more capable chip than the atmega328p, and yet (oddly enough) it's priced lower than the atmega328p. It's priced 95 cents/chip from Mouser/digikey in quantity 1, so there's no need to risk getting counterfeit atmega328p's from aliexpress or similar, which would probably cost more anyway.
